ELECTRIC FURNACE.

Application filed December 29, 1922. Serial No. 609,689.

To all whom it may concern:

Be it known that I, JOHN SoKoLowsKr. citizen of Poland, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have'invented certain new and useful Improvements in Electric Furnaces, of which the following is a specification.

This invention relates to stoves of the type which utilize electricity as the source of heat,

the invention having reference also to the provision of an electric stove, and of electric power generally, in places where a generator can be hydraulically operated, the invention having for an object the provision of a novel 16 type of electric stove combined with a water boiler.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the follow- 20 ing description and accompanying drawings,

and to the appended claims in which the various novel features of the invention are more particularly set forth.

, Fig. 1 of the drawings is a diagrammatic elevational view showing the means for generating the electric current.

Fig. 2 is a front View of the stove.

Fig. 3 is a side view thereof.

Fig. 4 is a diagram of the electrical connection.

Referring first to Figs. 2 and 3 of the drawings, my improved stove here comprises a lower portion 10 of rectangular shape and in which are several heaters, or burners ll of the usual type and located under an ordinary stove top 12. This lower member, or base, 10 is mounted on legs 13 carrying rollers 14 on their lower ends,

These rollers may, if desired run on asuitable track on the floor.

Extending upwardly from opposite sides of the base 10 are wall members 15 which have a box-like structure 16 on their upper ends in which. is an oven closed by a hinged door 17.

For heating water I provide a rectangular boiler 20 which is of substantially the size of the space enclosed by the side walls 15 between the stove top 12 and the upper member 16. This boiler is fixed at its back to a standard 21 suitably secured to the floor .so as to support the boiler. Extending upwardly through the boiler are tubes 22, of

- maticall switched into and out ofthe electric fee circuit as the stove is moved into and out of the position shown Fig. To this end a suitably insulated contact member 25 is mounted on the bottom of the boiler and is adapted to engage a suitably insulated contact spring 26 carried by the stove top 12. When the stove is moved forward, the space between the side walls 15 may form an oven, the front of the boiler 20 closing this space at the rear, while a hinged door 27 closes it at the front. A second door 28 may close an opening in the front of the stove for access to the burners.

In Fig. l of the drawing I have illustrated a means for generating electric current, to supply the stove. In this case water under pressure is derived from a suitably elevated collecting tank 30 and flows through a valve controlled pipe 31 to a water turbine 32 which drives. an electricgenerator 33 through a suitable connection indicated at 34. The current from the generator is used to charge a storage battery 35.

In Fig. 4; I have indicated the electrical connections of my improved stove. The leads from the generator to the battery are indicated at and 41, the lead 40 having a hand switch 42 therein. From opposite sides of the battery main loans 43 and 44 extend. Lead 43 separates int-o twobranclies dividualones of thetu'rnef cons 11,1 to the heating coils 23 as a unit, or to the two While I have shown and described a pre- {erred embodiment-of my invention it isto be understood that I do not limitmyself to the precise construction herein disclosed and that various changesand: modifications might be made therein Without departing i from the spirit and scope of the invention as defined in the appended claims.

Having thus described my invention What electric beating coils for said boiler, said boiler being formedswith vertical dues in 'which said heating coils are located, said base being movable fromunder said boiler,. and automatic-circuit closing means {or said Coils adapted to cause the circuit to said coils 'to' be opened andclosed respectively as the.

base is moved a'way froni' and under said boiler. 7'

. 2. A stove comprising a movable base, side Walls extendingmpward therefrom, a boxlike structure supported on the upper ends of said side Walls, a fixed boiler adapted to fit in the space between the said side alls,

and heating coils in said boiler.

, 3. A stove comprlsing a movable base, side.

like} structure supported on the upper ends of said side Walls, a fixed boiler adaptedto fitin the space between the said side Walls,

and heating coilsin said boiler, and contact members controlling the circuit to said coils.

and adapted to automatically engage and -ivalls extending upward therefrom, a box- I disengage as the base is moved Withrespect to the boiler. i

In testimony whereof I have aflixed 'my signature.
